Fig. 19 1s a front view of another form of my improved hanger-applied to the coverof a nduit junction box and. shown in the position in which it normally appears before the fixture is attached in position thereby. Fig. 20 is a view similar to Fig. 19, but with the hanger shown in position ready to receive the fixtureg," Fig. 21 is a longitudinal see-1 't ional view taken on line w -w of Fi 19'.

Fig. 22 is a view similar to Fig. 21,buts owing the hanger drawn forward. Fig. 23 is the hangen'which is adapted to be secured preferably by'screws 2 to a wall or ceilir'ig at the point where the conducting wires. (not 30 shown), are brought through the wall and where the fixture is to be hung. The conducting wires'are brought'through the wall around the sides of the base 1. The base 1 is provided with a rearwardly extending tubular portion 3 in which rests the shank 4 oif-the hanger H. which is located in front of the base 1. The base'l'is" provided with an opening'lG through. which the hanger shank 4 ext ds.

is in .its1inward..ppsition to prevent the hangerfrom turningQ'" A sprin 9 surrounds thevhanger shank 4 and its ends-rest against 95 the base 1 and a nut 10 screwed on theend of the shank, the purpose of which spring is angles'to thekeys'T; adapted to engage the, base 1. at the edge of; the opening 6 to limit the forward movement of thehanger. The

The hanger shank 4 is provided with eys 7 which fit in the key notches 8 of the opening 6, when the hanger ta s H comprises a head provided with outwardly diverging sides 15, hook mem-' ber 16 provided with a flange 16 at its up peredge, guide member 17 and flanges 18 for the purpose'ab'out to be described. The fix.-. ,t-ure E which is attached in position by my hanger is provided with 'a hanger engaging element comprisin a bar 20 secured to the fixture and provi ed with a. notch 21 in.

which the hanger H rests when securing the Fe; drawing the hanger'H forwardly and into .positionto receive the fixture I use a wrench W shown. in Fig. 23. The wrench is provided with a notch 26 which is adapted to fit around thehead 15 of the hanger so that, the hanger may be turned by thewrench and the edges 27 of the wrench around said notch are adapted to engage the flanges 18 sot-hat the hanger may be drawn forwardly. Y

The operation of the above descr bed form of my invention is as follows AssuIning that it is'desired to hang a fixture in position by my improved hanger and the hanger is in the position shown in Fig. 1 of thedrawing the wrench W is applied to the head 15 of the hanger-'11 so that the notch 26 fits around the head 15 and'theedges 27 engage the inner faces ofthe flanges 18. 'The hanger is then drawn forwardly byIthe' wrench against thetension of spring 9 until the lugs 11 engage the base 1 as shown in and the keys'7 are drawn into engagement" Fig. 11, in which position of the hanger the keys? are disengaged from the key notches 8 of the ope'ningGi'n the base 1 as shown in Fig.- 11. The hanger is then turned by the wrench 'into the position shown in Fig. 2 ofthe drawing to receive the fixture. The wrench is then removed from the hanger with the base member 1 by spring 9 as shown in Fig. 8 and the hanger-is maintained in said fixture receiving position by said spring. The fixture wires, (not shown),

are then connected to the conducting wires extending from the wall: The fixture 1s then placed over the hanger in such position that the notch'21 in bar 20 registers with the narrow part of the hanger head 15 between the sides 15, and the fixture is brought down 'upon; the -hanger, during which movement of. the-fixture the upper edge of the notch 21 engages the guide membar 17, whereby thebar 20 is tion of the bar-above the notch 21 rests on top of said headand the sides of the notch be 21 enga e the diverging sides 15*,0f the head 15 tightly so there canbe no relative movement of the fixture and hangers. The fixture is then turnedandj-the engagement of ".the"bar 20- at the sides of the -notches -21 with the head 15 causes the hanger H-also to turn'until the keys register with the key ided onto. 'the head 15 in' such position t at the por-- 12 j i i notches 8, whereu on the spring Q-dravvsth'e .hanger H invnar l and as said hunger i drawn jinwardly t e hook member 16a'nd. flanges 18 engage the bar 20 and draw the fixture firmly into position against the wall or ceiling.

The. form of my invention illustrated in Figs. 12 to 18 inclusive is adapted to heapplied'to' the fixture attaching element 30 within a conduit junction box B, into which the conducting wires (not -shown)- are brought'from the conduits. In this form of my invention the hanger H is-slidably and rotatably mounted upona slew 31 of.ii1-

saluting-material, which fits on a stud 32 projecting outwardly from a bolt 33 restingin a 'disk 34 of insulating material. The hanger H isprovided with a pair of inwardly projecting arms 35, each of which consists of two parts 35" and 35", the parts 35 being spaced farther apart than the parts-35? forming shoulders 35. The" disk 343s provided with 'a. pair of notches 37 in which the parts 35 of arms 35 are adapted to rest to prevent the hanger turning whensaid hanger is in. its inner position. The disk34 isalso provided with reduced portions 400%! which the parts 35 of arms 35 are adapted to be moved to enable the hanger H to 'be turned when drawn forwardly. The parts 35 of'arms 35 are" provided\with hook extremities 41 for engaging oneend of a spring 42, the other end of which rests against the disk 32L The head 33 of bolt 33 rests in a recess 34 of disk 34, whereby the disk is prevented from taming with relation to the bolt The sleeve 31 is providedwith anfinsulating\ flange 31 at its inner end adapted to cover said head to prevent the hanger coming in' contact with said head. The shank 45 of bolt 33 projects through anopening 46 in the end wall 47 of an insulating cup 48. An internally threaded cup .9 rests with in said insulating cup and is screwed on' to the endof bolt 33. The internally threaded portion of the cup 49; is adapted:to.screw. on to the threaded part 50 of the-junction box fixture attaching element 30 whereby the hanger is supported" the wrench W is applied to the hanger H in the same manner in which it is applied 'to the hanger H of Fig.1. The hanger is drawn; forwardly against the tension of spring 42 until the parts 35 of arms 35 are withdrawn from the notches 37 and the parts 35 ofi said arms are in registrylwith the disk reduced portions 40 and the shoulders 35 in front of the disk 34 as shown in shoulders 35 and arm 35.1-egister with the disk notches 37, whereupon the spring 42 raws the hanger H and fixture F inwardly until the fixture F is brought inte position against the wall, during which operation of the spring the parts 35 of arms 35 are v drawn into the notches 37, whereby the fixture is prevented from turning.

The' form of my invention illustrated in Figs. '19 to 2-2 incl usiye is adapted to be applied to a junction box cover 60. -The' cover is countersunk at 61, Fig. 21, and is provided with an opening 62, An insulata ing washer 63 rests within said countersunk portion 61 of the cover and is provided with an outer flange 64 and an innerifiange 65 -which rests within the opening 62 of said cover. A-cup '66 rests within the flange 65"; 0f Washer 63. The cup is provided with a flange 67 against which rests an insulating washer 68. The cup 66 is -threaded at 69 to receive a nut 70, which engages washer 63' and draws washer 68 into engagement with the countersunk portion-61 of the cover whereby the cup is maintained in posii tion on said cover; The nut is provided with holes 71 to receive a wrench by means of Wll1Cl'1 the nut is screwed onor off the i cup 66. The front wall of the cup 66 is provided with an opening 7 through which projects the shank 76 of, the hanger H Key notches 77 are formed in the sides of the opening '75 to receive the keys 77 on the forward end of the hanger shank '26, A

- nut 78. screws on to the inner end of the hangeifshank 76, and a'spring 79 surrounds the shank, the ends of which spring rest 're spectively against the front wall of the cup 66 and the nut 78. Said spring draws the hanger H inwardly. Lugs 80 are located on the shank 76, which are adapted to eng 'e the front wall of the cup 66 to limit" d the forward movement of the hanger. The

auction box B, Fig. 12 is provided with lugs 81 h: 'ing screw openings 82, in which -fit screws 83, which projectthrough slots 84 in'the cover 60 and secure the cover to the junction boxl' i tion is as follows Assuming that it is desired The operation of this form 6f my inven- 5 to hang a fixture on the hanger and the The fixture wires (not hanger is in the position shown in Fig. 19, the hanger H is first drawn forwardly by the wrench IV, in the manner in which" the hanger Hf is drawn forwardly by said wrench until the lugs engage the front wall of thecupGG and the keys 77 disengage the ke notches 77, (see Fig. 22). The

hanger is tien turned by the wrenclrinto:
